If Sally can paint a house in 4 hours, and John can paint the same house in 6 hours, how long will it take for both of them to paint the house together?
- A.
2 hours and 24 minutes
- B.
3 hours and 12 minutes
- C.
2 hours and 45 minutes
- D.
1 hour and 5 minutes
Correct Answer
A. 2 hours and 24 minutesExplanation
Sally can paint 1/4 of a house in 1 hour, while John can paint 1/6 of a house in 1 hour. To find out how long it will take them to paint the house together, we need to add their rates of painting. The combined rate is 1/4 + 1/6 = 5/12. To find the time it will take to paint the whole house, we take the reciprocal of the combined rate, which is 12/5. Converting this to hours and minutes, we get 2 hours and 24 minutes.Rate this question:

The sales price of a car is $12,590, which is 20% off the original price. What is the original price?
- A.
$14,310.40
- B.
$14,990.90
- C.
$15,290.70
- D.
$15,737.50
Correct Answer
D. $15,737.50Explanation
To find the original price, we need to determine the price before the 20% discount. We can set up an equation: original price - (20% of original price) = sales price. Let x represent the original price. The equation becomes x - 0.2x = 12,590. Simplifying, we have 0.8x = 12,590. Dividing both sides by 0.8, we find that x = 15,737.50. Therefore, the original price of the car is $15,737.50.Rate this question:

If Leah is 6 years older than Sue, and John is 5 years older than Leah, and the total of their ages is 41. Then how old is Sue?
- A.
8
- B.
10
- C.
14
- D.
19
Correct Answer
A. 8Explanation
Since Leah is 6 years older than Sue, and John is 5 years older than Leah, we can deduce that John is 11 years older than Sue. If we let Sue's age be x, then Leah's age would be x + 6, and John's age would be x + 6 + 5 = x + 11. The sum of their ages is given as 41, so we can write the equation: x + (x + 6) + (x + 11) = 41. Simplifying the equation, we get 3x + 17 = 41. Solving for x, we find that x = 8, which means Sue is 8 years old.Rate this question:

Jim is able to sell a hand-carved statue for $670 which was a 35% profit over his cost. How much did the statue originally cost him?
- A.
$496.30
- B.
$512.40
- C.
$555.40
- D.
$574.90
Correct Answer
A. $496.30Explanation
To find the original cost of the statue, we need to divide the selling price by 1 plus the profit percentage. In this case, the profit percentage is 35%, so we divide $670 by 1.35 (1 + 0.35). This gives us $496.30, which is the original cost of the statue.Rate this question:

Grace has 16 jellybeans in her pocket. She has 8 red ones, 4 green ones, and 4 blue ones. What is the minimum number of jellybeans she must take out of her pocket to ensure that she has one of each color?
- A.
4
- B.
8
- C.
12
- D.
13
Correct Answer
D. 13Explanation
To ensure that Grace has one jellybean of each color, she needs to take out the maximum number of jellybeans of the same color, which is 8 (red). Then, she needs to take out one more jellybean of each remaining color, which is 4 (green) and 4 (blue). Therefore, the minimum number of jellybeans she must take out is 8 + 1 + 1 + 1 = 11. However, since the question asks for the minimum number of jellybeans to ensure that she has one of each color, she must take out one additional jellybean, making it a total of 11 + 1 = 12.Rate this question:

- A.
$57
- B.
$90
- C.
$104
- D.
$112
Correct Answer
B. $90Explanation
If Lee worked 22 hours and made $132, we can find her hourly rate by dividing her total earnings by the number of hours worked. In this case, her hourly rate is $132/22 = $6. Therefore, if she works 15 hours next week at the same pay rate, she will make 15 * $6 = $90.Rate this question:

You purchase a car making a down payment of $3,000 and 6 monthly payments of $225. How much have you paid so far for the car?
- A.
$3225
- B.
$4350
- C.
$5375
- D.
$6550
Correct Answer
B. $4350Explanation
The down payment of $3,000 is the initial amount paid for the car. In addition to that, there are 6 monthly payments of $225 each, which totals to $1,350 ($225 x 6). To find the total amount paid so far, we add the down payment and the monthly payments: $3,000 + $1,350 = $4,350. Therefore, the correct answer is $4350.Rate this question:

Your supervisor instructs you to purchase 240 pens and 6 staplers for the nurse's station. Pens are purchased in sets of 6 for $2.35 per pack. Staplers are sold in sets of 2 for 12.95. How much will purchase these products cost?
- A.
$132.85
- B.
$145.75
- C.
$162.90
- D.
$225.25
Correct Answer
A. $132.85Explanation
To calculate the cost of purchasing the pens, divide the total number of pens needed (240) by the number of pens in each set (6). This gives us 40 sets of pens. Each set of pens costs $2.35, so multiplying 40 by $2.35 gives us $94. To calculate the cost of purchasing the staplers, divide the total number of staplers needed (6) by the number of staplers in each set (2). This gives us 3 sets of staplers. Each set of staplers costs $12.95, so multiplying 3 by $12.95 gives us $38.85. Adding the cost of the pens and the staplers together gives us $94 + $38.85 = $132.85. Therefore, the correct answer is $132.85.Rate this question:

Questions 16-19. In the sixteenth century, an age of great marine and terrestrial exploration, Ferdinand Magellan led the first expedition to sail around the world. As a young Portuguese noble, he served the king of Portugal, but he became involved in the quagmire of political intrigue at court and lost the king's favor. After he was dismissed from service to the king of Portugal, he offered to serve the future Emperor Charles V of Spain. A papal decree of 1493 had assigned all land in the New World west of 50 degrees W longitude to Spain and all the land east of that line to Portugal. Magellan offered to prove that the East Indies fell under Spanish authority. On September 20, 1519, Magellan set sail from Spain with five ships. More than a year later, one of these ships was exploring the topography of South America in search of a water route across the continent. This ship sank, but the remaining four ships searched along the southern peninsula of South America. Finally they found the passage they sought near a latitude of 50 degrees S. Magellan named this passage the Strait of All Saints, but today we know it as the Strait of Magellan. One ship deserted while in this passage and returned to Spain, so fewer sailors were privileged to gaze at that first panorama of the Pacific Ocean. Those who remained crossed the meridian we now call the International Date Line in the early spring of 1521 after ninety-eight days on the Pacific Ocean. During those long days at sea, many of Magellan's men died of starvation and disease. Later Magellan became involved in an insular conflict in the Philippines and was killed in a tribal battle. Only one ship and seventeen sailors under the command of the Basque navigator Elcano survived to complete the westward journey to Spain and thus prove once and for all that the world is round, with no precipice at the edge.

- A.
Rotor
- B.
Transformer
- C.
Capacitor
- D.
Series circut
Correct Answer
B. TransformerExplanation
A transformer is a device that is used to change the voltage and amperage of an electric current. It consists of two coils, known as the primary and secondary coils, which are wound around a common iron core. When an alternating current passes through the primary coil, it creates a changing magnetic field. This changing magnetic field induces a voltage in the secondary coil, which can be either higher or lower than the voltage in the primary coil, depending on the number of turns in each coil. Therefore, a transformer can step up or step down the voltage and amperage of a current.Rate this question:

When referring to an electronic circuit, AC stands for
- A.
Actuator Circulator
- B.
Alternating Current
- C.
Anterior Condition
- D.
Air Conditioner
Correct Answer
B. Alternating CurrentExplanation
AC stands for Alternating Current in the context of an electronic circuit. Alternating Current refers to the flow of electric charge that periodically reverses its direction. This type of current is commonly used in electrical power systems as it allows for efficient transmission of electricity over long distances. Unlike Direct Current (DC), which flows in only one direction, AC constantly changes its polarity, resulting in a sinusoidal waveform. This alternating nature of the current enables it to power various electronic devices and appliances efficiently.Rate this question:

Which of the following is not a form of precipitation?
- A.
Rain
- B.
Sleet
- C.
Fog
- D.
Hail
Correct Answer
C. FogExplanation
Fog is not a form of precipitation because it is composed of tiny water droplets suspended in the air, rather than falling from the atmosphere like rain, sleet, or hail. Precipitation occurs when water vapor condenses into liquid or solid form and falls to the ground due to gravity. Fog, on the other hand, forms when warm air cools and reaches its dew point, causing water vapor to condense into tiny droplets near the ground.Rate this question:
